Wanderers in the swamps of Taggelisk are warned to listen for the rattle of the nicori, which resembles that of some venomous snakes in the region and often precedes an attack. While rattlesnakes and sidewinders use their rattles largely to warn passing hoofstock of their presence, nicori will rattle at any non-prey animal they aim to attack, using it as a direct threat to frighten off adversaries and trespassers. This is not an idle threat, for nicori can range between two and seven feet in length and have been known to attack wild dogs. They lash out with sharp claws and long teeth, injecting a powerful venom if they are especially enraged. Wild nicori can be highly territorial, especially in places with few humans around, and may chase invaders from their nests into the territories of other nicori. This habit has given them a fierce reputation, so many travelers are surprised to see domestic nicori lounging around the stalls and docks of many riverside towns in Taggelisk. In places with plenty of pests to eat, nicori do not defend their territories and can become sociable animals, even allowing strangers to scratch their limber backs as they lie in the sun – though this is not recommended.

In the midst of the magewars, a legend appears that tells of stray magic wandering into a vast western swamp, turning native creatures grotesque and leeching into the soil to cause chaos. The most colorful retelling of this legend specifies that the small rat-like creatures in the swamp merged with local snakes to produce a new animal borne of corrupt magic. A similar story told by the people of Taggelisk has a lighter tone: once, mongooses were brought to Ageti to rid the city of snakes, but instead of killing them, the mongooses became enamored of the local snakes, and thus the nicori were produced. Whatever the truth may be, these peculiar creatures have intrigued travelers for generations. They have a fierce reputation and are well-revered for creatures of their size. While many parts of a nicori may be used for potions – the venom, rattle, sloughs, and fur all have magical properties – less familiar to foreigners is their value in controlling rodent pests. Despite their potent venom, adult nicori seldom bite humans, and with quick remedies sold in most markets, few in Taggelisk consider domestic nicori dangerous. Feral nicori are another matter entirely, though, and it is good advice to give the creatures a wide berth when encountered in the wild.
